Originally posted by smalcom December 9, 2024
Good day, everyone.

I'm trying to launch SPI1 under Arduino IDE. The transmission didn't work and I switched to direct control of the registers.

The problem is solved. By default, stm32duino sets the system clocking from PLL1P. And SPI1 cannot use this signal as a source. I switched SPI1 to clocking from PER_CK and everything worked.

SPI clock selection have to be explicitly done
and ensure frequency allows standard SPI freq
based on the SPI baudrate prescaler.

as oscillator. See Errata sheet.
